Are there any known bugs with chan file import for the terragen camera?
I think i found some but i want to make sure i am not using the program incorrectly or just running in to a limitation
of the preview tech version.

I am using the tech 2 preview to evaluate if we might be able to use Terragen 2 on a project. We know it is still a preview
but if we know that teh camera motions between Maya and T2 will work then, we can wait for a more mature T2.

So this is what I did.

I make a height field in T2 and exported it as a LWO.

Then I used Modo to convert the LWO in to a Ma file. (the scale is one to one between the two applications)

In Maya I placed a simple house on the terrain and exported its positional info via the ImportExportChan.mel script.
I also saved the simple house out as a OBJ.

Then i animated teh maya camera a bit & exported its animation using the above script.

I looked at teh chan files and the data seems to be correctly saved in them.

I started the  terragen two program & loaded the same project that i used to make the heightfield.

I went to the T2 camera settings and used the option on the bottom to import the chan file. First i rowsed tot eh file and then i selected "import chan file"...nothing happened. no animation was read in.

Then i went to the positional box for teh camera and selected the animation curve icon [the icon looks familiar ;)]

T2 informed me that 1 frame of animation had been read. and it seemed to read it properly.

Then i did the same for the camera's rotational settings..but this time T2 read in the positional info.

The free Technology Preview does not support animation. It sounds like this is probably why you're having problems and the animation info isn't being read correctly - it's disabled in the free version. To the best of my knowledge the .chan file import is otherwise working correctly, provided you have the registered Deep + Animation version.
